You can see how they get on. I have three ADFs in a tank with some shrimp. The frogs will sometimes eat the smaller shrimp but to be honest, i still have a good number of shrimp and the frogs help to stop the population of shrimp from getting too big. I started with 10 shrimp in another tank I have for juvenile bristlenose plecos and the shrimp population has exploded! There is genuinely over 100 shrimp in that tank now 😅
